Use the burst-mode enable command to enable the burst function.  

Use the undo burst-mode enable command to disable the burst function.  

By default, the burst function is disabled.  

The burst function improves packet buffering and forwarding performance in the following 

scenarios: 

z 

Dense broadcast or multicast traffic and massive burst traffic are present.  

z 

High-speed traffic is forwarded over a low-speed link or traffic received from multiple 

interfaces at the same speed is forwarded through an interface at the same speed.  

By enabling the burst function on your switch, you can improve the processing performance 

of the switch operating in the above scenarios and thus drop packet loss rate.  

 

z 

For packets to be forwarded properly, you must not enable the burst function when the 

XRN function is enabled. Refer to XRN Fabric Operation for detailed information about 

XRN.  

z 

Because the burst function may affect the QoS performance of your switch, you must 

make sure that you are fully aware of the impacts when enabling the burst function.
